Not able to access Microsoft products after installation

The installed Office edition must match the license you purchased: one-time licenses require apps downloaded directly from Microsoft, while Mac App Store versions of Word and Excel require Microsoft 365.^1^

1. Identify your purchase and account

Sign in at Microsoft Services & Subscriptions using the Microsoft account used to buy or redeem Office.

• Microsoft 365 subscription: Confirm that it is active, then open Word and sign in with that same account.
• Office 2024/2021/2019 or another one-time purchase: Confirm that the purchase appears in the account. Continue with section 2.
• Purchased through Apple’s Mac App Store: Continue with section 3.
• Nothing appears: Try any other Microsoft account you may have used. If you received a product key, it may still need to be redeemed and associated with an account before installation.^2^

2. If you bought Office with a one-time payment

Mac App Store Office applications cannot activate one-time licenses. Remove those apps and install the Microsoft-distributed version instead.^1^

1. Close all Office applications.
2. Open Finder → Applications.
3. Control-click Word, Excel, PowerPoint, and Outlook, then select Move to Trash.
4. Sign in at Microsoft 365 Apps using the account containing your Office purchase.
5. Select Install apps.
6. Open Finder → Downloads, run Microsoft Office installer.pkg, and complete installation.
7. Launch Word, select Get Started, and sign in with the purchasing account.^2^

3. If Microsoft 365 was purchased through Apple

An App Store-billed subscription depends on the Apple purchase receipt rather than only the Microsoft account sign-in.

1. Open System Settings → Apple Account → Media & Purchases → Subscriptions and verify that Microsoft 365 is active.
2. Confirm that the Mac App Store is signed in with the Apple ID that made the purchase.
3. Open the Office app and select Restore Previous Purchase.
4. If the subscription is active but restoration fails, contact Microsoft Support and retain the Apple purchase receipt. Microsoft documents this procedure for purchase-association failures.^3^

Do not replace the App Store version with the direct-download version merely because the subscription is Apple-billed; try Restore Previous Purchase first.

4. If the correct license still is not recognized

Reset the locally stored Office licenses:

1. Ensure that you know the Microsoft account and password associated with the purchase.
2. Quit every Office application.
3. Download Microsoft’s license removal tool.
4. Open the downloaded .pkg, select Continue, and complete the wizard. A Mac administrator password may be required.
5. Open Word or Excel and sign in using the account associated with the license.
6. After activation succeeds, restart the Mac.

The tool removes locally saved Office licenses; be prepared to sign in again afterward.^4^

If the message specifically includes 0x0 or License not found, first open Finder → Applications → Microsoft AutoUpdate and install all available Office updates. If the error remains, proceed with the license-removal steps above.^5^
